RTL8152B芯片与RK3028A配合使用，它由符合IEEE802.3u标准的MAC、USB控制器、内存、低压差线性稳压器等组成。主要应用于USB 10/100M以太网主板、电子狗、笔记本、扩充口、嵌入式系统等。
电子工程师应用RTL8152B/RTL8152BN时如在PBC布线、布局、电源选取、平面分割、缩减EMI中遵循一些基本原则，可为RTL8152创造一个低噪、稳电源、低电滋干扰的环境，可使RTL8152B/RTL8152BN的性能发挥得淋漓尽致。
RTL8152B：具有一个高性能的系统，需采用以下措施。
（1）、提供一个好电源，同时将开或关电源时回路产生的噪声减少至最小。
（2）、保持电源和接地噪声水平小于100mV。
（3）、在电源与接地之间使用大容量电容器。
（4）、使用0.1μF双耦合电容过滤电源和接地中的高频噪声。
（5）、尽可能近地将双耦合电容布置在RTL8152B/RTL8152BN旁（小于200mils）
（6）、电容采用小封装以减小封装电感

The Realtek RTL8152B 10/100M Ethernet controller combines an IEEE 802.3u compliant Media Access Controller (MAC), USB bus controller, and embedded memory. A linear regulator (LDO) is incorporated for reduced BOM cost.
With state-of-the-art DSP technology and mixed-mode signal technology, the RTL8152BN offers high-speed transmission over CAT 5 UTP cable or CAT 3 UTP (10Mbps only) cable. Functions such as Crossover Detection and Auto-Correction, polarity correction, adaptive equalization, cross-talk cancellation, echo cancellation, timing recovery, and error correction are implemented to provide robust transmission and reception capabilities. The RTL8152BN features embedded One-Time-Programmable (OTP) memory.
Advanced Configuration Power management Interface (ACPI)—power management for modern operating systems that are capable of Operating System-directed Power Management (OSPM)—is supported to achieve the most efficient power management possible. In addition to the ACPI feature, remote wake-up (including AMD Magic Packet and Microsoft Wake-Up Frame) is supported in both ACPI and APM (Advanced Power Management) environments.
The RTL8152B supports Microsoft Wake Packet Detection (WPD) to provide Wake-Up Frame information to the OS, e.g., PatternID, OriginalPacketSize, SavedPacketSize, SavedPacketOffset, etc. WPD helps prevent unwanted/unauthorized wake-up of a sleeping computer.
The RTL8152BN supports ‘RealWoW!’ Technology which enables remote wake-up of a sleeping PC through the Internet. This feature allows PCs to reduce power consumption by remaining in low power sleeping state until needed.
Note: The ‘RealWoW!’ service requires registration on first time use.
The RTL8152BN is fully compliant with Microsoft NDIS5, NDIS6 (IPv4, IPv6, TCP, UDP) Checksum features, and supports IEEE 802 IP Layer 2 priority encoding and IEEE 802.1Q Virtual bridged Local Area Network (VLAN). The above features contribute to lowering CPU utilization, especially benefiting performance when in operation on a network server.
The RTL8152B supports Protocol offload. It offloads some of the most common protocols to NIC hardware in order to prevent spurious wake-up and further reduce power consumption. The RTL8152BN can offload ARP (IPv4) and NS (IPv6) protocols while in the D3 power saving state.
The RTL8152B supports the ECMA (European Computer Manufacturers Association) proxy for sleeping hosts standard. The standard specifies maintenance of network connectivity and presence via proxies in order to extend the sleep duration of higher-powered hosts. It handles some network tasks on behalf of the host, allowing the host to remain in sleep mode for longer periods. Required and optional behavior of an operating proxy includes generating reply packets, ignoring packets, and waking the host.
The RTL8152B supports IEEE 802.3az-2010, also known as Energy Efficient Ethernet (EEE). IEEE 802.3az operates with the IEEE 802.3 Media Access Control (MAC) Sublayer to support operation in Low Power Idle mode. When the Ethernet network is in low link utilization, EEE allows systems on both sides of the link to save power.
The device also features USB 2.0 technology. It provides higher bandwidth and improved protocols for data exchange between the host and the device. In addition, USB 2.0 offers a more aggressive power management feature that enables selective suspend to save energy.
The RTL8152B is suitable for multiple market segments and emerging applications, such as desktop, mobile, workstation, server, communications platforms, docking station, and embedded applications.
